Executive Summary

In September 2002 Outback Ecology services was commissioned by Tectonic Resources Pty Ltd

to conduct a vegetation survey of the area likely to be impacted by the development of the

Trilogy deposit on Myamba farm. Myamba farm is located approximately 25km south of

Ravensthorpe on the Hopetoun-Ravensthorpe Road. The purpose of the study was to provide

pre-feasibility data encompassing a vegetation and weed survey in the area.

The remnant woodland areas surrounding the proposed pit location were surveyed via four 100

square metre plots, to determine representative floristic and structural data of the area.. A

literature search for Declared Rare Flora was also completed by the Department of Conservation

and Land Management.

Four species of Eucalypts, were identified in the four plots surveyed on the Myamba form.

These included Eucalyptus scyphocalyx, E. phenax subsp. phenax, E. suggrandis subsp.

suggrandis and E. kessellii. E. pleurocarpa was not included in the survey but was noted in a

small patch of remnant vegetation near the proposed pit area.

The absence of mid stratum vegetation on the farm appears to be predominantly due to grazing

pressures. Grazing of grasses had occurred recently in most transects, and this made

identification of some species impossible.

There were a number of plants of Carduus sp. (thistle) on the cleared paddocks in the study area.

This species is generally described as an alien species, which is a serious problem in agricultural

pastures in Western Australia as they compete with pasture plants for resources (Department of

Agriculture, 2002).

There was no declared rare or priority flora (DRF) located on the Myamba farm, although nearby

the Kuliba reserve may contain some DRF as described in the CALM study (Appendix B).

Drainage lines on the Myamba farm appear to run in the direction of the Kuliba reserve.

Therefore there is potential for contamination of the Kuliba reserve via the Kuliba river.

A number of recommendations were suggested by Outback Ecology to minimise disturbance of

the ecosystems on, and surrounding the Myamba farm.

1.0 Introduction

In September 2002 Outback Ecology services was commissioned by Tectonic Resources Pty Ltd

to conduct a vegetation survey of the area likely to be impacted by the development of the

Trilogy deposit on Myamba farm. Myamba farm is located approximately 25km south of

Ravensthorpe on the Hopetoun-Ravensthorpe Road. The purpose of the study was to provide

pre-feasibility data encompassing a vegetation and weed survey in the area. The survey was

completed on the 19th of September.

1.1 Climate

The climate of the Ravensthorpe area (including Hopetoun) is typically dominated by hot dry

summers and cold wet winters. Mean maximum daily temperatures range from 16.2°C in July

to 29.2°C in January. Mean daily minimum temperatures range from 6.6°C in August to 14.5°C

in February (Bureau of Meteorology (BOM), 2002). In the twelve months prior to this study

(September 2001 – August 2002) a total of 352mm of rainfall was recorded, which was

approximately 72mm below average rainfall (Figure 1).

1.2 Flora and Vegetation

The survey area was located in the Eyre Botanical District within the Esperance Plains Region,

as classified by Beard (1990). Vegetation in the area is dominated by Scrub and Mallee heath on

the sandplains with scattered eucalypts. The ranges in the Ravensthorpe area are characterised

by Eucalyptus presissiana, E. lehmannii and Dryandra quercifolia whereas hill slopes are

dominated by E. nutans and E. gardneri. Woodlands in the area where typified by E. loxophleba

and E. salmonophloia (Beard 1990). There is one endemic species in the area (E. stoatei)

1.3 Topography and Soils

The topography of the area consists of sandy clay plains with quartzite ranges. The soils of the

Eyre Botanical District were generally described as sand overlaying clay and ironstone gravels

(Beard 1990).

2.0 Materials and Methods

Stacey Coxall and Jodie Costello of Outback Ecology Services undertook a vegetation

assessment at the Myamba farm on the 19th of September. Aerial photographs provided by

Tectonic Resources were used to locate remnant patches of vegetation within the proposed

disturbance area. The remnant woodland areas surrounding the proposed pit location were

surveyed via four 100 square metre plots, to determine representative floristic and structural data

of the area, with transects used to calculate crown cover within these plots. Plots were marked

on this aerial map (Figure 2), easting and nothings are located in Table 1. The surrounds of the

remnant areas were traversed by foot to locate any plant species not represented in the surveyed

areas.

A literature search for Declared Rare Flora in between the following co-ordinates 33°44’ -

33°51’S and 120°9’ - 120°16’E was completed by the Department of Conservation and Land

Management (CALM, Appendix B). These co-ordinates covered the Myamba farm and

surrounding areas, including the Kuliba reserve. The literature search was undertaken in regard

to:

• CALM’s Threatened (Declared Rare) Flora database,

• the Western Herbarium Specimen database for Priority species opportunistically collected in

the area of interest, and

• the Department’s Declared Rare and Priority Flora List.

3.0 Results

3.1 Trilogy 1

Vegetation on the Trilogy plot 1 was sparse open mallee forest (McDonald et al. 1998). There

was no middle storey vegetation at this site and one lower storey species (Bromus catharticus)

which was heavily grazed, but the density of this grass was high. Three mallee species were

recorded in the survey, and included, Eucalyptus scyphocalyx, Eucalyptus phenax subsp. phenax

and Eucalyptus suggrandis subsp. suggrandis. Upper stratum (mallee species) had a crown

cover of approximately 56% in the plot, while the lower stratum species (Bromus catharticus)

had a crown cover of approximately 4%. There was one weed species (Carduus Thistle)

recorded in the plot, with a moderate density.

The plot was dissected by a shallow creek bed with sandy white alluvial material in the lower

areas (Plate 1). In the higher areas the soil was a clay, with a high organic matter content. There

was a significant amount of litter present, suggesting relatively high plant produc tivity and good

soil quality.

Plate 1. Plot TRL1 located on the Myamba farm.

3.2 Trilogy 2

The vegetation at this site was also mallee woodland with a total crown cover of 48%

(McDonald et al. 1998). The vegetation at this site was dominated by Eucalyptus phenax subsp.

phenax and Eucalyptus suggrandis subsp. suggrandis (Plate 2). Three grass species,

Bromus catharticus, Austrodantonia setacea and an unidentifiable grass species, were recorded

in the vegetation plot with a total plant cover of approximately 5%. Generally most grasses were

heavily grazed and therefore barely recognisable. Vegetation at this site was generally healthy

with abundant new growth.

The soil at this site was organic grey clay. There were no weed species noted at this site.

3.3 Trilogy 3

The vegetation community of this plot was open mallee woodland (McDonald et al. 1998).

There were three species of Eucalypt which contributed to the crown cover of 16% at this site

(Plate 3). Eucalyptus suggrandis subsp. suggrandis, E. scyphocalyx and E. kessellii were all

present. Density of the tree species was approximately 5 species per plot (100 square metres),

and was composed mainly of Eucalyptus scyphocalyx. The lower stratum of vegetation at this

site had a cover of approximately 12% and included species 1 and species 3. There was no mid-

storey (between 1m and 2m) within the transect.

This plot was located close to the farm dam, with trees close to the dam appear to be stressed or

dying. Soils in the area were dark grey/brown loams.

density.

3.4 Trilogy 4

Vegetation at the Trilogy 4 plot consisted of an mallee woodland of Eucalyptus scyphocalyx,

E. phenax subsp. phenax and E. suggrandis subsp. suggrandis. The total crown cover of the area

was approximately 34%. The density of upper stratum species (mallee) was approximately 16

plants per 100 square metres. The lower stratum of the site was dominated by

Bromus catharticus and Panicum species with a cover of approximately 3.5%.

The soil at this site consisted of a light brown clay, and was very compacted at a depth of 2cm.

3.5 Declared Rare Fauna (DRF)

A total of 66 declared and rare and priority flora species were identified as likely to occur within

a six kilometre radius of the farm, although no DRF were found on the farm (Table 2). The

following is a list of the number of species for each conservation code. Generally the majority of

species in the area were Priority 2 and 3. A full description of the conservations codes, species

name and locations are presented in Appendix B.

The conservation categories are described below:

R: Extant, rare and in danger of extinction or otherwise in need of special protection.

P1: Poorly known, from <5 populations which are under threat.

P2: Poorly known from <5 populations which are not believed to be under immediate

threat.

P3: Poorly known from several populations although not believed to under immediate

threat.

P4: Described as rare, but adequately surveyed and not threatened.

4.0 Discussion

Four species of Eucalypts, were identified in the four plots surveyed on the Myamba form.

These included Eucalyptus scyphocalyx, E. phenax subsp. phenax, E. suggrandis subsp.

suggrandis and E. kessellii. E. pleurocarpa was not included in the survey but was noted in a

small patch of remnant vegetation near the proposed pit area (Figure 1). There were

approximately 25 plants in total at this stand of vegetation. These Eucalyptus were all described

as mallee species, which were less than 5m tall and formed a lignotuber (CSIRO, 2002).

Generally all mallee species recorded in the study were healthy (with the exception of those

surrounding the dam at Trilogy 3) and dense. Those species located around the dam appear to be

suffering from the effects of waterlogging and possibly salinity.

The absence of mid stratum vegetation on the farm appears to be predominantly due to grazing

pressures. Grazing of grasses had occurred recently in most transects, and this made

identification of some species impossible.

There were a number of plants of Carduus sp. (thistle ) on the cleared paddocks in the study area.

This species is generally described as an alien species, which is a serious problem in agricultural

pastures in Western Australia as they compete with pasture plants for resources (Department of

Agriculture, 2002). The seed of this species is designed with a parachute which is very effective

for wind dispersal.

There was no declared rare or priority flora (DRF) located on the Myamba farm, although nearby

the Kuliba reserve may contain some DRF as described in the CALM study (Appendix B).

Drainage lines on the Myamba farm appear to run in the direction of the Kuliba reserve.

Therefore there is potential for contamination of the Kuliba reserve via the Kuliba river which

runs to the east of the proposed mine. There were nine species of Extant taxa recorded in the

study. These are species which have been extensively searched for and are described as rare and

close to extinction. These species generally need special protection.

4.0 Recommendations

The following is a list of recommendations made as a result of this baseline study. Implementing

these recommendations will reduce the impact of mining in the Myamba study area.

With regards to the vegetation survey;

• Clearing – Vegetation clearing should be minimised to those areas of the tenement

required for operations. The removal of vegetation may result in wind/dust erosion if the

soil surface is not adequately covered.

• Topsoil Stockpiles – Stockpiled topsoil should be stored for a limited time as seed

viability and biological soil processes deteriorate with time. Topsoil stockpiles should be

approximately 1 - 1.5m in height to enable soil aeration and limit seed deterioration.

• Revegetation – The use of provenance seed should be undertaken in all site revegetation.

• Exploration Rehabilitation – The ripping of all gridlines after the exploration programme

should invigorate plant colonisation and establishment in these areas. All drill holes

should be capped with the PVC collars removed to minimise the entrapment of native

fauna. Similarly, costeans should be filled to avoid fauna injuries.

• Any seepage or discharges to creek should be monitored to minimise risk of

contamination to downstream vegetation (particularly Kuliba reserve).

• Care should be taken to avoid exposing existing vegetation to waterlogging or salinity.

Local changes in hydrology appear likely to have impacted on native trees near the dam.
